As explained in the subject, the Auctex distribution now on elpa is broken.

I reverted to the version downloadable on the archives of last october, and it works back
perfectly.

Best,

That's very unfortunate.  Could you please provide some more details
about what exactly is broken?  I.e., what error do you get?  Or what
doesn't work anymore which has worked with the previous version?

Thanks,
Tassilo

Essentially nothing worked, in the sense that it gave me an error in entering the LaTeX
major mode (a void definition of a symbol's function, unfortunately I do not remember
which function, since then I reverted to the latest stable distribution). The mode I was
then using for the file was a sort of broken LaTeX mode, not working properly (C-c C-c and
C-c C-a where both not working, for example). I tried to reinstall the elpa package
several times, and the issue was always the same.

No one else is reporting such a problem? If not, I can reinstall the package and test it
for you, but since I use AucTeX for my work, I cannot do it right now.

All the best,

Not until now.

No problem, do it whenever you have time.

  - Update to the current ELPA auctex release
  - Fire up a new emacs
  - Do M-x toggle-debug-on-error RET
  - Find a latex file

Then a buffer with the backtrace should pop up when the error happens
pinpointing the exact location of the problem.  That's what we need.

It would also be good to get some more system information (Emacs
version, AUCTeX configuration, etc.).  For that, do M-x
TeX-submit-bug-report RET RET and copy and paste the information below
the dashed line into your reply to this report.

Dear Tassilo,

I attach here both the debugger backtrace report, and the system information, as you
asked.

Hope it helps.

Indeed, we have restructured quite a lot in font-latex.el in the last
ELPA release, and now font-latex-extend-region-functions is gone.
However, there is no font-latex-extend-region-backwards-lemma-envII in
AUCTeX.  Do you use some extension package providing that function?  Or
is that in your ~/.emacs?

Hi Tassilo,

Yes I have this function in my .emacs (since very long time, I forgot about that, I

Well, what those functions did was fontifying the contents of all
theorem and lemma environments in font-latex-doctex-documentation-face,
i.e., stuff like

  \begin{theorem}
    I am fontified in font-latex-doctex-documentation-face.
  \end{theorem}

You can create such environments with the ntheorem package, i.e.,

  \usepackage{ntheorem}
  \newtheorem{theorem}{Theorem}
  \newtheorem{lemma}{Lemma}

but it is a user's choice to name the environments theorem or lemma
(though possibly you are using that convention).

FWIW, I'd suggest to remove this customization entirely and check if it
is allright for you to have theorem/lemma bodies fontified normally.

If you feel like something deeply loved is missing then, I can rewrite
your code to match the new font-latex business.

Tassilo

Hi Tassilo,

I happily removed that function, and now everything is back to normal as you suggested.

I use the function to fontify in equations (that keeps working), but not the one that
fontifies theorems and lemmas, so I have not lost anything in removing that.

Many thanks for the very useful feedback!

That's good news.  I'm therefore closing this bug report.
